A method for manufacturing a composite metal alloy. An Mg material as an alloy base material and a carbon nanomaterial are mixed together to obtain a mixture in which the Mg material is covered with particles of the carbon nanomaterial. The mixture of the Mg material and carbon nanomaterial are sintered to obtain an Mg sintered compact including the carbon nanomaterial. The Mg sintered compact including the carbon nanomaterial is dissolved to obtain a melt of the composite metal alloy.

A composite plated product has a metal material and a plating film of compounded carbon nanomaterials and microparticles coated on the metal material in a nickel plating bath in which carbon nanomaterials are mixed together with microparticles having an average grain size of 2.5 &#x3bc;m or less.

Composite plated product

A composite-plated article has a metallic material and a plating film coated on the metallic material in a nickel-plating bath containing carbon nanocomposite fibers. Each of the carbon nanocomposite fibers is formed of a carbon nanofiber core and microparticles that react with carbon to form a compound bonded to a surface of the carbon nanofiber core.

A carbon nanocomposite material comprises a carbon nanomaterial and Si powder having an average particle diameter of 10 &#x3bc;m or less vacuum-vapor deposited on a surface of the carbon nanomaterial as a film of SiC. The film of SiC has an average thickness in the range of 10 to 50 nm.

Carbon nanocomposite material comprising a SiC film coating, and method of manufacturing the same

In a method for manufacturing a composite-metal-forming material, heating a metal material a Mg alloy or an Al alloy is heated to a temperature in a region where a solid and a liquid are both present to thereby yield a semi-molten metal material in a semi-molten state. An additive material is introduced to the semi-molten metal material and kneading is performed to obtain a composite metal material. The composite metal material is heated to a solution temperature of the metal material and a solution treatment is performed to thereby yield a composite-metal-forming material. The additive material introduced is a carbon nano-composite material formed by mixing a carbon nanomaterial and a metal powder to obtain a carbon nano-composite metal powder, compacting the carbon nano-composite metal powder into a solid to obtain a preform, heating the preform in a vacuum, inert gas, or non-oxidizing gas atmosphere to a temperature in a region where a solid and a liquid are both present, and applying pressure to the heated preform.

A composite plating layer contains carbon nanofibers. A composite plating solution contains a Watts bath composed mainly of nickel sulfate and nickel chloride, a brightening agent, a surface active agent and carbon nanofibers. Polyacrylic acid is used as the surface active agent.

Fibrous nanocarbon and metal composite and a method of manufacturing the same

A method for manufacturing a composite metal material combined with a nanocarbon material comprises heating a metal alloy to a half-melted state in which both liquid and solid phases are present. Next, a nongraphitized nanocarbon material is added to the half-melted metal alloy and stirred to form a composite metal material combined with a nanocarbon.
